Last year, the number of armed conflicts in the world increased markedly, with the strongest increase taking place in Sub-Saharan Africa. This is the conclusion in a new report by researchers at the Uppsala Conflict Data Program (UCDP), published in the Journal of Peace Research. UN Secretary-General Ban Ki-Moon has presented the statistics to the UN General Assembly in his report on international mediation.

The conflict data stems from the internationally recognized conflict data program at the University of Uppsala (UCDP). For almost 10 years, UCDP has published an annual conflict update in collaboration with the Peace Research Institute Oslo (PRIO) and PRIOs Journal of Peace Research.

Following a year (2010) that signaled hope for a more peaceful development, the number of conflicts increased by nearly 20 percent, from 31 to 37. Last year’s jump in conflicts deviates from the long-term trend line, which shows that the world is gradually becoming more peaceful.

“It should be pointed out, however, that even though we have now witnessed the largest increase between any two years since 1990, the number of conflicts is still far below the peak levels of the early 1990s,” says Professor Peter Wallensteen, head of the UCDP. At the peak 53 armed conflicts were active.

2011 also saw an increase in the most severe conflicts. Six conflicts were categorized as wars, passing the level of at least 1,000 battle-related deaths. This is up from four in 2010. While the wars in Afghanistan, Libya, Pakistan, and Somalia have received much media attention, the intense conflicts in Sudan and Yemen have been less covered.
